more about zayin
I also placed the zayin at the end of the word.
My point is not to prove kosher or posul,my point is we are splitting hairs on a safek deorayta.
most of us when showing an etrog to a rav and he slightly twitches his nose we are out there buying a new one.
First all of the magihim should send back such mezuzos to the sofer, as "SOFEK PSUL"
Is an Aguna involved that we are splitting hairs to save the mezuza when the sofer clearly violated the beraysa? THE BRAYSA MEANT OUR SHAILA the braysa didnt come to warn us not to make a zayin with 3 kulmusim.
What bothers me even more is when i ask sofrim why is the vav shorter than the zayin, they often reply "i was worried the vav will become a nun sofit" it is embarrassing when a sofer clearly ignores the beraysa that warns no short vavs and no long zayins and sets up his own policy of chumros.
